To the Editor: Clarfield (1) listed Alzheimer disease, multi-infarct, depression, alcohol, and drugs as important causes of the dementias. The causes of the reversible dementias were drugs, depression, and metabolic conditions. I report a case that shows an additional cause for reversible dementia.
An 82-year-old man with a history of excised colonic carcinoma and angina was hospitalized after having had weight loss and progressive mental confusion for 3 months. A comprehensive evaluation showed no evidence of metastatic disease, metabolic disease, a structural neurologic abnormality, or medication effect. A neurologic consultation concluded that he had a "degenerative syndrome" of unknown cause.
